Ancient IBM Thinkpad 2603 dropped off at my office today

A customer of mine came by the office today and dropped off this ancient laptop, an IBM Thinkpad 2603. I tried to find specs on it to no avail. The screen is about 7.5 inches by 4.5 inches. Cool IBM Netbook, huh? I was able to find one on Ebay for 99 cents. Check out the pictures of the 2603 below:
